SPECIFICATION forming part of Letters Patent No. 772,972, dated October25, 1904. Application filed August 31, 1903. Serial No. 171,429. (Nomodel.)

rTo @ZZ whom, it may concern:

Be it known that I, FEN'roN E. STILWELL, a citizen of the United States,and a resident of Monteur Falls, in the county of'Schuyler and State ofNew York, have invented a new and useful Improvement in Hot-WaterHeaters, of which the following is'a specification.

My invention relates to an improvement in hot-water heaters, the primaryobjectbeing to provide an improved -apparatus especially adapted forbarber shops or other places where it is desired to heat water quicklyfor the purpose of washing, sterilizing, or similar purposes. n

Another object is to provide an apparatus which can be attached orcoupled to the usual water system in order to facilitate 'its operationand insure a perfect circulation'and adequate supply of water at alltimes.

With. these objects inview my inventionconsists in certain novelfeatures of construction and combinations of parts, which vwill theclaims.

In the accompanying drawings, Figure .1 is a vertical section, partsbeing shown in elevation, and Figs. 2, 3, and i are details'.

A represents the main cylinder of myimf- This is made of sheetY provedwater-heater. metal'and preferably mounted on legs 1 1, whereby it issupported at a suitable elevation above the floor or other means uponwhich it rests. Extending vertically through the cylinder from top tobottom is thecone-shaped chimney 2, and this is connected' at theupper'` and lower ends to the upper and lower ends of the cylinder bylmeans of fiangedcircular plates 8 and 4, the iianges of which areriveted or otherwise secured to the upper and lower edges of thecylinder and cone, as shown in' Fig. 1; At the bottom the oil-lamp B islocated, it being provided with a waterreceptacle 5 on top, adapted toreceive water whereby to prevent the oil from becoming overheated fromlthe burner above. An inverted-cone-shaped cap surrounds the burner andextends to the bottom of the cylinder, it being adapted to prevent theescape of heat from the burner and applyit to the bottom of the cylinderand direct it upward through center of the cylinder by way of theconeshaped chimney 2. Just above the cylinder water-tank 7 is located,it being suiiiciently removed from the cylinder to admit of the freecirculation of the heated air beneath it and betweenit and the top ofthe cylinder A, as well as around the tubes 8 8, which convey the waterfrom the cylinder as it becomes heated to the tank 7 above. A jacket 9of greater diameter than the tank and cylinder surrounds the latter,resting loosely at its upper edge upon the tank and depending at itslower edge beyond the upper edge of the cylinder. In this way the heatis made to circulate around both ends of the cylinder A, centrallythrough it, around the tubes 8 8, beneath the bottom and around thesides of tank 7, and

around the upper end of cylinder A for a short distance, escapingdownwardly at the outlet lO. In this way a maximum amount of heat isconfined, directed, and concentrated over a maximum area of the surfaceof the cylinder .and water-tank, so that the water is quickly andeffectually heated and caused to circulate.

. The hot water may be drawn out through an ordinary faucet (not shown)into a stationary `water-bowl or other receptacle (not shown) throughpipe 11. Gold wateris suppliedffrom the service-pipe 12, it beingdischarged into the cylinder, as indicated at 13, somewhere near thelower endof the cylinder.

From the foregoing it will be seen that a 'simple and inexpensiveapparatus is provided for heatmg water and sterilizing purposes,

and the heating may be accomplished by the use of an ordinary oil-lamp.The' apparatus may be connected with the water system or it might beself-contained and portable if preferred. .Provision is made by means ofa mica or glass panel 21 in the cap 6A by which to examine the conditionof the flame from time to time without removing the lamp' for thatpurpose. Byrthe raising and lowering of the jacket 9 thel opening forthe outlet of the products of combustion mightbeadjusted. It will alsobe observed from the disclosure made that the' entire amount of heat isutilized, applied, and distributed, so as to heat and circulate thewater and maintain the heat while the lamp is lighted.

It is evident that slight changes might be resorted to in the form andarrangement of the several parts described without departing from thespiritv and scope of my invention, and hence I do not wish to limitmyself to the exact construction herein set forth; but,

Having fully described my invention, what 1 claim as new, and desire tosecure by Letters Patent, is-

1. The combination with a cylinder having a passage therethrough forproducts of combustion, a tank and pipes connecting the two and spacingthem apart whereby acirculatingchamber is provided between them, of ajacket supported `on the tank, inclosing the latter and the upper end ofthe cylinder and spaced from the tank and cylinder whereby the productsof combustion extending up through the cylinder are caused to circulatethrough the space between the cylinder and tank, around thecommunicating' tubes and the sides of the tank vand l to dischargedownwardly around the upper end of the cylinder.

2. The combination with a cylinder having a chimney theretlnmigh, a lampand a cap which latter extends from the burner and embraces the bottomof the cylinder throwing the heat in contact with the bottom of saidcylinder and the walls of the chimney, ol a tank located a shortdistance above the upper end of the chimney and top of the cylinder,said tank in communication with the cylinder and a jacket which restsloosely upon and surrounds and is spaced from the tank whereby to directheat from the chimney to the outer surfaces of the tank and to preventits .surface from being chilled from the outside.

In testimony whereof l have signed this specification in the presence oftwo subscribing witnesses.
